Abstract: In one embodiment of the present invention, a method for using a domain specific computer language to extend an existing computer language is provided, comprising: creating a rule for validation for a compiler, the rule for validation created in a rule description language created specifically to describe rules for validation, the rule defining a part of the domain specific computer language; examine source text to identify a domain specific language to use for compiling; and compiling the source text using a compiler for an existing computer language using the identified domain specific language, wherein the compiler contains a rules interpretation engine that runs the rules for validation for the identified domain specific language, wherein the rules for validation are external to the compiler.

Abstract: In an embodiment of the present invention, event handlers are used to trigger actions based on events occurring on a data stream. A process of the present invention involves creating the event handler, which may be embodied in, for example, software. The creation of the event handler involves parsing all of the rules in a manner that allows events themselves to trigger actions that will ultimately involve evaluation of rule and, if necessary, firing of those rules.

Abstract: A stream of hot air passes from a combustion chamber through an application gun to a preheated substrate. A powdered thermoplastic is fed into the application gun. The hot air stream heats the powdered thermoplastic to its fusion temperature and transports it to the substrate.

Abstract: Isotope separation apparatus consisting of a plurality of cells disposed adjacent to each other in an evacuated container. A common magnetic field is established extending through all of the cells. A source of energetic electrons at one end of the container generates electrons which pass through the cells along the magnetic field lines. Each cell includes an array of collector plates arranged in parallel or in tandem within a common magnetic field. Sets of collector plates are disposed adjacent to each other in each cell. Means are provided for differentially energizing ions of a desired isotope by applying energy at the cyclotron resonant frequency of the desired isotope. As a result, the energized desired ions are preferentially collected by the collector plates.
